About 2 years ago, I had one of those “AHA” moments when I saw a physician from France demonstrate the use of blunt cannulas for injecting dermal fillers. Since then, I have hardly used the traditional needle method for fillers and my patients love it. I have become one of the strongest advocates of this technique, and it has revolutionized my thoughts about fillers.
Blunt cannulas have a rounded tip and are very flexible. The advantages are:
- The bruising and swelling post procedure are dramatically reduced. So you don’t have the social downtime after having your lips done (which can be up to 2 weeks). Blood vessels bounce off the tip and are not injured as easily with the cannulas.
- Procedural discomfort is much improved in most areas.
- With only 2 entrance “pokes”, I can enhance the lips, vs. at least 10 pokes using needles.
- Overall time of procedures are significantly reduced. Because I’m not using topical anesthesia in most cases, the total time to have your smile lines injected can be only a few minutes. Under eye injections are the same. In and out of the office more quickly and then go to lunch.
- The risk of a vascular catastrophe is almost eliminated because you can’t enter a vessel with a blunt cannula. You can still compress a vessel, but this is a much easier problem to deal with than an intravascular injection. So BLUNT CANNULAS ARE A MUCH SAFER WAY TO INJECT DERMAL FILLERS.
- I can inject the upper lip lines, lips, nasolabial folds, marrionette lines, and lower cheek, all through the same entrance site.
- Tear trough injections can be done deep to the muscle to avoid the filler from showing (“Tindel Effect”)
- I can use the cannulas for all fillers except Sculptra.

The only area which I might use a needle to inject filler now is along the vermilion border of the lips and for superficial fine lines or scars.
When choosing a physician for filler, technique makes a world of difference…ask my patients.
